EMBROIDERY-HOOP.

Specification of Letters Patent.

Patented se t. 24.1912.

Application filed January 18, 1911. Serial No. 603,241. w

To all whom it may concern Be it known that I, MARTIN L. KEAGY, acitizen of the United States, residing at Canton, county of Stark, andState of Ohio, have invented certain new and useful Improvements inEmbroidery-Hoops, of which the following is a specification.

My invention relates to embroidery hoops and particularly to embroideryhoops formed of sheet metal.

More specifically, my invention relates to improved means for connectingthe ends of the hoops.

The object of my invention is to provide a sheet metal embroidery hoopwherein the two ringsmay be freely passed one over the other and thensecurely clamped to-hold the work.

Afurther object of myinvention is to provide a device of the classmentioned whereby the clamping action of the rings rmay be adjusted orregulated at will to suit the nature of the work.

Other objects will appear hereinafter.

With these objects in view my invention consists generally in anembroidery hoop ring formed of a strip of material bent into circularform and clamping means adjustably connecting the ends of the strip. Myinvention further consists in an embroidery hoop comprising a pair oftelescopic rings, one or both of the rings being split and provided withmeans whereby it may be clamped upon the other ring.

My invention further consists i1 1,various details of: construction andarrangements of parts all as will be fully described hereinafter andparticularly pointed o-utin the claims. My invention will be morereadily understood by reference to the accompanying drawings forming apart of this specification and in whichy V Figure 1 is a plan view,partially in section, of a connection between the ends of the ringembodying my invention in its preferred form, Fig. 2is an elevation ofthe same, Fig. 3 is a transverse section on the line 3'-3 of Fig. '2,Fig.4 is a view similar to Fig. 1 illustrating a modified form of myinvention, Fig. 5 is an elevation of the device shown in Fig. 41, Fig. 6is a plan view of a device similar to that shown in Fig. 1 but appliedto the inner ring of an embroidery hoop and illustrating the ends of thering partially separated,- Fig. 7 is an elevation of the same, and Fig.8 is a plan YIBW Of the same with the ends connected 11. normalposition.

Referring now to the drawings 1 indicates the outer ring of anembroidery hoop and 2 the inner ring, each formed of sheet metal andhaving the edges rolled forming heads 2 and preferably curved intransversecross section as shown 1n FigL3, the rings having convex andconcave co-acting faces respectively as indicated. The rings are whatare known as split rings and their ends are well rounded on the innerside as at 4 to prevent in ury to the work. I

Toone end of the ring is secured a guard or casing 5. This comprises abody portion 6 having its edges curled to form base flanges 7 which. fitwithin the heads 3 as learly shown in Fig. '3. The casing 5 proectsbeyond the end of the ring to which it is secured and the base flanges 7of the projectin portion telescopes freely within the bea ed portion ofthe opposite end, whereby a sliding connection is had between the endsof t e ring. A

Fixed to the opposite end of the ringfrom 8. This is preferably curvedconcentrically wlth the ring and its free end extends into end portionof the rod 8 is threaded; as at 10 and upon this threaded, portion isaknurled wheelor nut 11 the periphery of,

which extends slightly beyond the outer face of the casing 5. The casingisstamped out of sheet metal and formed with ya recess 12 forthe nut 11and with .inturned flanges 13 forming the walls of said recess and end'that to which the casing 5 is secured is a rod flanges 14. The. walls offlanges 13 form" thrust "members for the nut 11 and it is obvious thatby turning said nut'the ends of p of the threaded portion thereof. Thespring normally tends to draw the rod out of the casing and therefore toexpand the ring. The casing 5 prevents the thread with which theoperator is. working from catching in the rod or spring.

In Figs. 6, 7, and 8 I have illustrated a device similar to that abovedescribed but arranged upon the inner ring of the hoop. It is obviousthat when used upon the inner ring it must be located upon the innerface thereof. The construction is identical with that described for theouter ring except that the spring 15 is a. compression spring instead ofa tension spring, whereby the tendlelncy of the spring is to contractthe inner oop.

In Figs. 4 and 5 I have illustrated a modified form which may be appliedto either the inner or outer ring but have illustrated it in conjunctionwith the outer ring only. In this form the nut 11. is dispensed with andthe rod 8 instead of being threaded is provided with a head 1? betweenwhich and the outer Wall 14 of the casing is interposed a compressionspring 18. The tendency of the spring 18 is to draw the rod within thecasing to contract the size of the ring. When the adjusting nut 11 isused the clamping action of the ring may be varied at the will of theoperator, but with the form illustrated in Figs. 4 and 5 the clampingaction is due entirely to the spring. Either or both rings of anembroidery hoop may he provided with clamping device as desired. Inoperation, wlen a device on;- hodying the 11 is used, the nut is turneduntii the ring; is the proper size to pass freely over or within theother hoop as the case may he and after the hoops are telescoped withthe work between them the nut is turned inthe opposite direction toclamp the hoops one upon the other. 'With the form shown in Figs. 4 and5 the hoop is merely expended against the tension of the spring and.after being passed over the other ring and the work is released, thespring up said rod and flanges formed on saidcasing constituting thrustmembers for said nut, substantially as described.

2. In an embroidery hoop, a split ring, a. casing fixed to one end ofsaid ring a threaded rod fixed to the opposite end of said rm andextendin into said resin there being a recess formed in sail casing,

knurled nut in said recess and threaded upon said rod, trust members forsend nut upon each side thereof, ends spri having one end secured tosaid rod and the other end secured b0 said casing and adapted to expandsaid ring, substantially as described. in testimony whereof I havesigned my name to this specification in the presence be two subscribingwitnesses.
